What is the use of thin strip moving behind the main scale of vernier caliper?
That is the intelligent technique applied by Vernier. We have seen 1 cm gap. That has been divided into ten equal parts. So each part is 1 mm. That too could be sensed. Even that 1 mm could be divided into two equal halves with markings. But now we need 1/10 of a mm. Will it be possible to have such 10 equal gaps within that 1 mm gap? No not at all possible. But I'd like to measure such a fine distance. What can I do? Now let us take 9 mm and divide that length into 10 equal parts. That markings could be done easily. Now each gap would be 0.9 mm. As we keep the extreme end marking ie 0 reading of vernier along with 0 of main scale, then the other extreme would coincide with 9 mm marking. Ok what about first division of vernier? It will be just before the 1 mm marking by a gap 1-0.9 = 0.1 mm. So as we slide the vernier through small distance such that first division of vernier coincides with 1 mm marking, then we are so sure that we have slided the vernier by 0.1 mm. See we have succeeded in getting even that 0.1 mm so accurately without direct markings. That is the intelligence of mankind inherent by nature.
What are the errors in micrometer screw gauge?
This micrometer has zero error.The zero marking on the thimble is below the datum line. So this micrometerhas a positive zero error.In this case we will take the reading on the thimble.Thimble reading = 0.03 mmSo the micrometer has a zero error of +0.03 mm.Whatever reading we take on this micrometer we would have to subtract +0.03 mmThe zero marking on the thimble is above the datum line. So this micrometerhas a negative zero error.In this case we will have to count the number of divisions on the thimble between the zero marking and the datum line.No. of divisions = 3Measurement of each division = 0.01mmSo the micrometer has a zero error of -0.03 mm.Whatever reading we take on this micrometer we would have to subtract -0.03 mm
What is the kind of force static electricity makes?
make pieces of paper then take a plastic scale and rub it on your hair and then take it near the pieces, observe ans : the pieces of cloth flies in the and sticks to the scale this is called STATIC ELECTRIC FORCE
How many scale measurements does it take to know which of eight balls weighs the most?
seven measurments
How does a spring balance work?
to measure the weight of an object, hang the object on the hook of the balance, lift up the balance and take the reading. OR to measure the force needed to pull an object, attach an object to the hook of the balance, pull the balance and take the reading when the object moves.
How do you take reading in travelling microscope by using the vernier scale reading from 0.6 to 1.0?
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
How do you take reading in traveling microscope?
let us think with all our common sense.The indicator which reads the reading on the main scale is the zero mark on the vernier.On the main scale each mm is divided into half mm. Hence the reading would be read for divisions on the main scale. ie say I start from 3 cm.3 cm, 3.05 cm, 3.1 cm, 3.15 cm, 3.2 cm, 3.25 cm and so on.But for our convenience let us read as 3.000 cm, 3.050 cm, 3.100 cm, 3.150 cm, 3.200 cm, 3.250 cm and so on,Now say your indicator ie zero marking on the vernier is lying in between say 3.200 and 3.250 cm. Then main scale reading would be recorded by taking the lower value namely 3.200 cm.Now the vernier would give the last two decimal values for accuracy. If the 43rd division on the vernier get coincided with some line on the main scale, then the vernier reading will be got by multiplying this vernier coincidence 43 by the least count. The least count will usually be 0.001 cm.So the vernier scale reading will be 0.043 cmNow by adding this along with the main scale reading ie 3.200 cm we get 3.243 cm.Another example: If suppose the indicator lies in between 6.450 and 6.500. The vernier division 17 get coincided.Main scale reading is 6.450 cmVernier scale reading is 0.17 cmSo the total reading ie accurate reading is 6.467 cmUNNATI CHANDANESTD:XII
How do you avoid parallax error when taking a meniscus reading?
By keeping Ur eyes perpendicular to the vernier and main scale while taking the measurement.

How would you take a measurement for a sample of 0.2 mol dm-3 CuSO4 if the reading was off the scale?
no
What is used of vernier bevel protractor?
it's used to take angle measurement
How do you figure axle weight on semi truck?
You take it to a scale and weigh it out. If you don't have something available like a Cat scale, which can give individual weights for each group of axles, you drive until the steer axle is on the scale, and get a weight reading from that. Then you pull forward until your drive axles are on the scale, and get a reading from that. Subtract the weight reading you got from your steer axle, and you've got the weight for your drive axles. Then you pull completely forward, until your trailer axles are on the scale, as well. At this point, you'll have your total weight. Subtract the previous weights (steer plus drive axle weights), and you'll have your trailer axle weight.
What is the main purposes of reading?
You read fiction because it can take you places where you would never dream of going. But the truth is its all in your head!
What are four questions you should be aware of when actively reading poetry?

What is the multiplication factor in watt meter?
wattmeter is constructed such that it read only power on a single scale. Only single scale will avilable to read the measured power. In order to take the acuurate reading just we measure the reading and we will multiple along with factor called multificaion factor. That's depends on on which voltage knob we connected and also the current. Multification factor can be dtermind by: Multification factor =(voltage range*current range*pf)/Max scale deflection...
What is the reading level of a sixteen year old student?
Well first i need your reading level scale. But i can read any books, but if it is Shakespeare or anything like Shakespeare i cant read. The man makes no sense. Why do i have to take a whole british literature course!? This stuff is stupid
Which of these is a way to describe the main idea?
The main idea is the central point or theme that the text is trying to convey. It is the most important message or conclusion that the author wants the reader to take away from the reading.
